Abstract

본 발명은 무선 통신 시스템에서 단말이 하향링크 제어 정보를 수신하는 방법에 관한 것이다. 보다 구체적으로, 향상된 하향링크 제어 채널(Enhanced Physical Downlink Control Channel, EPDCCH)의 공통 검색 영역(Common Search Space, CSS)상에서 특정 참조 신호(Reference Signal, RS)를 수신하는 단계를 포함하며, 상기 특정 참조 신호는, 초기 접속(Initial Access) 절차에서 상기 제 1 단말에 대하여 할당된 위치가 제 2 단말에 대하여 공통적으로 적용될 수 없는 경우, 펑쳐링(Puncturing)되어 전송되는 것을 특징으로 한다.
